Accessory renal arteries - a source of hypertension: A case report

Table 1 A summary of demographic, radiographic, and clinical information from a review of six previously published cases of secondary hypertension due to accessory renal artery pathology

Ref.	Clinic	Imaging	Treatment	Follow-up
[13]	5-year-old boy with severe hypertension (BP 190/130 mmHg) partially uncontrolled with propranolol, diuretics and spironolactone	Arteriogram: an elongated, nonstenotic aberrant artery arising from the common iliac artery feeding the lower pole of the right kidney	Partial nephrectomy and resection of the aberrant artery at its origin	One month later: BP 120/70 mmHg without any medication
[13]	16-year-old girl with severe hypertension (BP 220/115 mmHg) partially controlled with metoprolol 100 mg/day and hydrochlorothiazide 50 mg/day)	Arteriogram: a nonstenotic aberrant artery arising from the lower aorta supplying the lower pole of the left kidney	Medical treatment with captopril, diuretics and a ß-blocker	Generally, well controlled under medical treatment;Lost to follow-up at 19 years old
[15]	29-year-old patient with hypertension uncontrolled with amlodipine 10 mg and atenolol 50 mg daily (BP 160/100 mmHg)	Digital subtraction angiography: left accessory renal artery entrapped by the diaphragmatic crus with 90% stenosis of the proximal ostial segment	Medical treatment	Close monitoring of the patient’s BP and consideration of further invasive and aggressive treatment in case of prolonged uncontrolled hypertension
[12]	21-year-old female with severe hypertension (BP 220/142 mmHg) without relevant previous medical history	Renal magnetic resonance angiography: bilateral accessory renal arteries were seen superior to the main renal arteries; Renal angiography: no stenosis in the main or accessory arteries bilaterally	Medical treatment with spironolactone 75 mg and amlodipine 10 mg daily	BP control achieved with medication
[12]	41-year-old woman with history of hypertension for 3 years partially controlled with amlodipine 5 mg daily (BP 145/100 mmHg)	Renal magnetic resonance angiography: bilateral small accessory left renal arteries supplying the upper pole of the kidney; Renal angiography: no stenosis in the accessory arteries	Medical treatment with spironolactone 50 mg and oral potassium chloride 1.2 mg daily	BP control achieved with medication
[14]	31-year-old female with reported history of elevated blood over the past 7 years (BP 150/100 mmHg)	Renal ultrasound: left accessory renal artery; Renal CT: ostial stenosis of the left accessory renal artery	Medical treatment with amlodipine 10 mg and lisinopril 5 mg	BP control was achieved with lisinopril 10 mg, and amlodipine was discontinued
